Police have never been interested unless someone is hurt and if not, take no details and do t turn up.

Yes you should tell your insurance, but am sure it is noted as you being more likely/prone to be involved in an accident and so a higher risk.

As you are doing her a favor I would insist it goes to that bodyshop straight away, the work is quoted and if agreed, paid upfront to the garage on the day the car goes in.
